Discharge from 3 into the cooking chamber. That is, the water stored in the adsorbent 2 humidifies the inside of the cooking chamber.

Then, by repeating the first step and the second step alternately, humidification can be efficiently performed. In this way, by using the water contained in the indoor air for humidification, it is possible to perform humidification at all times without the need for water supply, and it can be used as a humidifier while the microwave oven is stopped. In addition, if the second step described below is performed first,
Since the adsorbent 2 is sufficiently dried, adsorption can be efficiently performed in the first step.

[Dehumidification in Cooking Room] The first step (drying of the adsorbent) will be described. As shown in FIG. 5, when the microwave oven is stopped, the humidity control apparatus 1 is moved and the suction side damper 4 is moved.
When 0 is set to F and the discharge side damper 41 is set to C, the indoor air is sucked into the humidity control apparatus 1 from the indoor suction port 60 by the fan 50. Then, after the room air is heated by the heater 30, the water contained in the adsorbent 2 is separated by passing through the adsorbent 2 to become humidified air and the indoor discharge port 6

Next, the second step (dehumidification in the cooking chamber) will be described. As shown in FIG. 1, the suction side damper 40 is D,
The discharge side damper 41 is set to the position A, and the cooking chamber suction port 62
The air in the cooking chamber is sucked into the humidity control apparatus 1 by the fan 51.

In FIG. 6, the air in the cooking chamber (the temperature of the air in the cooking chamber is high due to the movement of the microwave oven) is sucked into the humidity controller 1 by the operation of the blower fan 50, and is adsorbed. After passing through the material 2, the indoor discharge port 61
From the room. This is referred to as an air flow M.

On the other hand, at the same time as the above-mentioned operation, the indoor air (which has a temperature lower than that of the air in the cooking chamber) is sucked into the humidity control apparatus 1 through the indoor suction port 60 by the operation of the blower fan 51, and the adsorbent 2 is absorbed. It passes through and discharges from the indoor discharge port 63 into the cooking chamber. This is referred to as an air flow N.

At this time, in the adsorbent 2, the air flow N exchanges sensible heat with the air flow M via the adsorbent 2 and receives moisture from the adsorbent 2 to heat it. The humidified air becomes humidified air and is discharged from the cooking chamber discharge port 63. On the contrary, in the adsorbent 2, the air flow M exchanges sensible heat with the air flow N via the adsorbent 2, and the adsorbent 2 adsorbs moisture and removes heat.

In FIG. 7, reference numeral 50 ′ is a fan that is connected to the indoor discharge port 61 and can blow air in both directions inside and inside the humidity control apparatus 1, 32 is a heater that heats the indoor air sucked from the indoor discharge port 61 by the fan 50 ′, 51 ′ Is a fan that is connected to the discharge port 63 in the cooking chamber and can blow air in both directions inside and inside the humidity control device 1.

Further, the adsorbent 2 is constructed as shown in FIG. 3B, and the discharge side damper 41 is moved to the position B.
When the suction side damper 40 is at the position E, the ventilation surfaces of the adsorbent 2 are in two directions that are orthogonal to each other without being mixed.

The operation of the second embodiment will be described below with reference to FIGS. 8 to 9. The operation of the second embodiment can be the same as that shown in the first embodiment.

[Total Heat Exchange Ventilation] Below, as shown in FIG. 7, the flow of air when the discharge side damper 41 is in the B position and the suction side damper 40 is in the E position is shown in FIG. It demonstrates using. As shown in FIG. 8, when the microwave oven is moving, the flow of air M is caused by the forward rotation operation of the fan 51 ′.
Occurs, and at the same time, the forward rotation operation of the fan 50 ′ causes a flow N of air.

Then, sensible heat exchange is performed between the air flow M and the air flow N via the adsorbent 2, and the air in the cooking chamber having a high temperature gives heat to the room air and also gives moisture. Indoor discharge port 6
Discharge from 1. On the other hand, the heated and humidified air is discharged from the cooking chamber discharge port 63 into the cooking chamber.

By performing the total heat exchange ventilation operation as described above, it is possible to cook an uncooked food while ventilating during cooking without lowering the temperature in the cooking chamber of the microwave oven. In the above operation, all the heaters 30, 31, 32 are stopped, but since the microwave oven is moving, the air in the cooking chamber is at a higher temperature than the indoor air. , Sensible heat can be exchanged.

[Circulation Total Heat Exchange Ventilation] In the state shown in FIG.
While the microwave oven is moving, the fans 50 ′ and 51 ′ are normally rotated and the heater 30 is energized, whereby the air flow N is humidified by the adsorbent 2 and becomes humidified air, which is discharged into the cooking chamber. Flow M is dehumidified by the adsorbent 2 and becomes dry air, which is discharged into the room.

After performing the above operation for about 5 minutes, the following reverse feeding process is performed. As shown in FIG. 9, the energization of the heater 30 is stopped, the fans 50 ′ and 51 ′ are rotated in reverse, and the heater 32 is energized. As a result, an air flow M ′ from the indoor discharge port 61 to the cooking chamber suction port 62 is generated, and an air flow N ′ from the cooking chamber discharge port 63 to the indoor suction port 60 is generated.

After the air flow M'is heated by the heater 32, it is humidified by the adsorbent 2 and becomes humidified air which is discharged into the cooking chamber, while the air flow N'is dehumidified by the adsorbent 2. It becomes dry air and is discharged into the room.

That is, when the air flow N shown in FIG. 8 is performing the humidifying operation, the air flow M is performing the dehumidifying operation. On the other hand, when the air flow N ′ shown in FIG. 9 is performing the dehumidifying operation, at the same time, the air flow M ′ is performing the humidifying operation. In this way, even if the humidity circulates and the blowing direction is changed,
Since the humidity of the food to be cooked is always ensured, even if water that is difficult to be exchanged is generated between the first adsorption path and the second adsorption path of the adsorbent 2, the air flow is reversed in the blower path. By sending, it is possible to promote the separation of moisture that is difficult to be exchanged from the adsorbent, and to perform efficient humidification and dehumidification.

[Third Embodiment] The third embodiment of the microwave oven of the present invention will be described below. The same parts as those of the first and second embodiments are designated by the same reference numerals and the description thereof will be omitted. Omit it.
